This document includes the following sections:

•	Resource View - outlines the document types by which resources are organized.

•	Resources by Document Category - lists resources for each document category outlined
in the Resource View.

•	CFR View - provides relevant Code of Federal Regulations (CFR) language reformatted
for easy reading.

These three main sections are cross-referenced, i.e., each section includes hyperlinks to the other
sections. In addition, each section and its accompanying index include a hyperlink to the Main

About the Compendium

The Hazardous Waste Generator Regulations Compendium serves as a user-friendly reference to
assist regulators, industrial facilities generating and managing solid and hazardous wastes, and
the general public in locating resources relevant to specific regulatory topics within the federal
hazardous waste generator program.

The objective of this document is to consolidate and streamline the various resources on a topic
into a user-friendly format, including references to relevant CFR language, Federal Register (FR)
notices, documents posted on RCRA Online (i.e., guidance in the form of memoranda issued by
EPA, Q&As, and other publications), and other resources, such as Frequent Questions webpages.
The Compendium has been divided into multiple volumes that are available here:
www.epa.gov/hwgenerators/hazardous-waste-generator-regulations-compendium.

This document does not change any of the existing solid or hazardous waste requirements, nor
does it offer an exhaustive list of relevant resources, as new resources may come into being or
older ones may be relevant to a specific issue, but not included. Certain available resources, such
as superseded RCRA Online documents, have not been referenced. Rather than including or
reproducing referenced resources, this document generally provides hyperlinks to individual
resources. As an exception, the Compendium does include relevant sections of the most current
CFR regulatory language (as of the date on the cover of the Compendium). The included CFR
language has been reformatted to make it easier to read, but it is not a substitute for the official
CFR itself, or for the requirements in the CFR. The Government Printing Office frequently
updates the e-CFR website; where appropriate, hyperlinks to the respective CFR section at the e-
CFR website are provided.

Most states are authorized to administer their own RCRA Subtitle C hazardous waste program.
Therefore, states may have their own set of regulations that apply in lieu of federal regulations.
State regulations must be at least as stringent as the federal standards, but they can be more
stringent. Please visit the following website to determine if the state regulatory program is
different from the federal program: https://www.epa.gov/hwgenerators/links-hazardous-waste-
programs-and-us-state-environmental-agencies, and check with your state agency.

About the Generator Treatment Volume

This volume of the Compendium lists resources and CFR language pertaining to generator
treatment that are found at 40 CFR 268 Subpart A and in the preamble to the March 24th, 1986
Federal Register Notice. For more information regarding other topics that apply to facilities
generating hazardous waste, refer to other volumes of the Compendium and EPA's Hazardous
Waste Generators Webpage.

Please note that the Hazardous Waste Generator Improvements rule of 2016 created new sections
in Part 262, which contains the regulations pertaining to generators. Accordingly, some citations
in the generator requirements in older resources in this Compendium are outdated, including
references to § 261.5, § 262.34, and others. Please see the preamble to the final Hazardous Waste
Generator Improvements rule for a discussion of the reorganization of the regulations (81 FR

§ 268.7(a)(5) Requirements for Generators and Reverse Distributors

View Resources | Go to e-CFR | Return to: CFR Index | Resource View | Main Index

(5) If a generator is managing and treating prohibited waste or contaminated soil in tanks;
containers; or containment buildings regulated under 40 CFR 262.15; 262.16; and 262.17
to meet applicable Land Disposal Restriction (LDR) treatment standards found at § 268.40;
the generator must develop and follow a written waste analysis plan which describes the
procedures they will carry out to comply with the treatment standards. (Generators treating
hazardous debris under the alternative treatment standards of Table 1 to § 268.45; however;
are not subject to these waste analysis requirements.) The plan must be kept on site in the
generator's records; and the following requirements must be met:

[§ 268.40 (a) - A prohibited waste identified in the table "Treatment
Standards for Hazardous Wastes" may be land disposed only if it meets the
following treatment standard requirements:

(1)	"total waste standards" - all hazardous constituents in the waste
or in the treatment residue must be at or below the values for that
waste found in § 268.40;

(2)	"waste extract standards" - the hazardous constituents in the
extract of the waste or in the extract of the treatment residue must
be at or below the values outlined in § 268.40;

(3)	"technology standard" - wastes must be treated using the
technology specified in § 268.42.]

(i)	The waste analysis plan must be based on a detailed chemical and physical
analysis of a representative sample of the prohibited waste(s) being treated and
[must] contain all information necessary to treat the waste(s) in accordance with
the requirements of this part; including the selected testing frequency.

(ii)	Such plan must be kept in the facility's on-site files and made available to
inspectors.

(iii)	Wastes shipped off-site pursuant to this paragraph must comply with the
notification requirements of § 268.7(a)(3).

[§ 268.7(a)(3)(i) - With the initial shipment of waste to each treatment;
storage; or disposal facility; the generator must send a one-time written
notice to each treatment; storage; or disposal facility receiving the waste;
and place a copy in the file.]

(III)(E)(1) - Under today's final rules, 100-1000 kg/mo generators will be required
to obtain a permit if they treat or dispose of hazardous waste on-site (except for
treatment in tanks or containers during the 180/270 day accumulation period in
conformance with Subparts J or I of Part 265, respectively) or accumulate
hazardous waste on-site in tanks or containers for more than 180 (or 270) days.

[•••]

The Agency disagrees that on-site treatment should be encouraged by exempting
those generators of 100-1000 kg/mo from the RCRA permitting requirements. To
the extent that these generators are conducting the same treatment/storage or
treatment/disposal as other permitted facilities, their on-site treatment activities
pose a potential risk to human health and the environment. Therefore, reduced or
eliminated permitting requirements would be inappropriate.

Of course, no permitting would be required if a generator chooses to treat their
hazardous waste in the generator's accumulation tanks or containers in
conformance with the requirements of § 262.34 and Subparts J or I of Part 265.
Nothing in § 262.34 precludes a generator from treating waste when it is in an
accumulation tank or container covered by that provision. Under the existing
Subtitle C system, EPA has established standards for tanks and containers which
apply to both the storage and treatment of hazardous waste. These requirements
are designed to ensure that the integrity of the tank or container is not breached.
Thus, the same standards apply to a tank or a container, regardless of whether
treatment or storage is occurring. Since the same standards apply to treatment in
tanks as applies to storage in tanks and since EPA allows for limited on-site
storage without the need for a permit or interim status (90 days for over 1000
kg/mo generators and 180/270 days for 100-1000 kg/mo generators), the Agency
believes that treatment in accumulation tanks or containers is permissible under
the existing rules, provided the tanks or containers are operated strictly in
compliance with all applicable standards.
